Multiple powers In

How does the 3 multiple power inputs perform? I assumed A is main, B is secondary if A is missing. And C is the last one if A and B are missing. Out of curiosity, I hooked up Amp meters in-between and noticed if all three powers are applied, they share the amps in-between each other. I thought they would be isolated from each other inside the HXr.

My thoughts are, A is powered from Main Bus. B is powered from Aux Bus, and C is powered from standalone backup battery. Leaving them all connected directly without switches in-between would allow fail-over without human intervention.

I believe they are identical. Most of the current will be drawn from the input with the highest voltage. Current will not flow backwards, out one of the inputs.
